To aZZ whom t may conce/m:

Be it known that I` ROBERT Lint WRIGHT,

.a citizen of theUnited "States, and resident of Los An eles, county of Los Angeles, and

' State of.- alifornia, have invented certain new and'useful Improvements in Projectiles; and I do hereby declare lthat the :toldl `lowing is a full, clear, and exact description f thereof.F

This invention is ,a modified form of my inventions filed in the United States Patent Oliice and known by Serial Numbers 4as follows: Nos. 186,296, 218,796, 218,797, 219,391, 221,005, $231,849, 235,482, 237 ,698,-and relates toV shells and projectiles. f 1 The particular object of this inventionis to prov'lde a shell pointer 'or projection having a removable percussion cap therein. Another object of my invention ls'to provide a shell pointer or projection having a channel for explosives therein. A The valueand objects of my lnventlon will be fully understood'from the JrollowfA ing descr'ption taken in connection wlth-the drawing, which shows a longitudinal sectional view of my invention. h The gure showsan explosivef'projectlle or shell .14 with acharge 3 therein, a slim shell pointer or projectlon l1 extending outof the point-of the projectile or shell and 5 is a removable piece screwed ont the endof the shellpointer or projection. firing pin is indicated at 6 in operative position to explode the percussion cafp 10, Wh n said firing pin is struck. The ring pin 1s provided with fa point the forward part of which is 'indicated at and is-n'ormally" held inf inoperative position .by the set screw 8 or other suitable means. The set screw may be removed when desired, hereby a'ording access to the firing pin. l. The shell pointer or projection is provided with a channel orbore 11, as shown, in which ,any suitable explosive or chargeinay be placed. It will be noted'that the part off` the channel -or bore which lextends `into 'the projectile is enlarged 'as at 13 in order that -f a greater quantity of ,explosivev may be placed therein and also that the thicknessI of the shellointerv or projection around this part of c annel or bore isreduced for ,an obvious purpose. .Y Y Y A light-tube 18 is secured adjacent thev rear of the shell pointer or projection for containing the explosive' 17. A cap. holder 10 "for the primer cap is removably held.

in the shell ointer or ro'ection as shown. If desired, tliis cap hollerland cap may be removed and a solid blank piece inserted 1n heu .thereof in order that the shell pointer or pro]ect1on may be rendered safe for hanmg. lA removable plug is indicated at -12 being provlded with a shoulder .21 against which the 'shell pointer abuts. The light tube 18 is held in place by threads 16 as shown. 'A` plug 1s provlded at 2 for the purpose of4 loading the projectile.v The operation ofthe device is as follows:

When the capon the firing pin is struck, the

"ringpin is ldriven inwardthereby explodlng the cap 10. The explosives iii-channel or bore 11 are thereby ignited, which' ignites the explosives 13,-I the latter causing the charge 17 the the light tube 18 to be setoi',

thereby firing the main charge of explo# s1ve 3. Y

The device may be very readily manufactured, .is sure of operation and is eiiic'ient, If des1red,`1-f or shlpping or other purposes lthe shell pointer or projection may be re- Y moved by VAunscrewing it from the plug 12, after which a dummy plug may be inserted Y until it is desired that the projectile orshell be used'.

` It is obvious that those skilled in the art may vary the details of construction as Well as the arrangement of parts Without departing from the spirit of the invention, and therefore I do not wish to be limited to the above disclosure except as may be required by the claims, What I claim. as v new and desire to secure by Letters Patent is 1.
